Homework Statement
A small sphere with a charge of 2.36 microCulombs is attached to a relaxed horizontal spring whose force constant is 88.6 N/m. The spring extends along the x axis, and the sphere rests on a frictionless surface with its center at the origin. A point charge Q = - 8.55...
Yippee! Finally got part c correct. I guess I was thinking too much into it... Thanks for your help :biggrin:
For parts a and b. They are equal because of Newton's Third law of motion which states that forces come in pairs and the forces in a pair act on different objects. So, for any object...
Hey Tiny-Tim!
Yay! I finally got part a) what a relief!
Thank you for your help!
Im still stumped on part c)... it appears to me that by adding the forces in parts a and b you would get the net force that is being asked for in part c)... but that's not the case.. I am still getting the...
Hi tiny-tim!
I really appreciate you taking the time to work with me on this.
Im still confused... unfortunately :confused:
In order to submit my answers to these problems I am using an online homework website, and I keep getting the answers wrong.
For part a)
(a) What is the net...
Thank you so much for replying! But I'm sorry I'm still confused (I'm very new at this so you will have to forgive me!)
For part a) it is asking the net force exerted by the car on the trailer.. and because the car is 1300 kg and the acceleration is 2.00m/s squared then I am not sure why I...
Homework Statement
On vacation, your 1300 kg car pulls a 540 kg trailer away from a stop light with an acceleration of 2.00 m/s2.
(a) What is the net force exerted by the car on the trailer?
(b) What force does the trailer exert on the car?
(c) What is the net force acting on the car...
Nevermind! I got the answer :)
What I was doing wrong was not taking into account the affect of the weight on the Net force.
By determining the weight of the T-Rex in Newtons (3710)(9.8) = 36358 and subtracting this number from the original net force 256700 - 36358 = 220342 N then taking that...
Homework Statement
Paleontologists estimate that if a Tyrannosaurus rex were to trip and fall, it would have experienced a net force of approximately 256,700 N acting on its torso when it hit the ground. Assume the torso has a mass of 3710 kg.
(a) Find the magnitude of the torso's upward...
